A document purporting to be a GPT-5 system has been leaked on the GitHub platform and has attracted widespread attention. This comprehensive prompt covers user alignment, anthropomorphic design, and output quality, among other aspects, totaling an impressive 17,803 tokens – a truly massive scale.
According to the latest reports, the alleged GPT-5 prompt documentation was disclosed by GitHub user Ásgeir Thor Johnson. Johnson has been organizing and sharing various leaked model prompts on this platform, and the GPT-5 prompt is undoubtedly the most significant release of his collection. Since the release of the document, it has quickly become the focus of much discussion among tech enthusiasts.

Through a careful study of this prompt, it has been discovered that GPT-5 is exceptionally well-considered in its design. It not only emphasizes high-quality output but also incorporates robust safety mechanisms to prevent the generation of harmful content or the leakage of user privacy. GPT-5 also features a highly anthropomorphic style, enabling it to interact with users in an enthusiastic, sincere, and warm manner, thereby significantly enhancing the user experience. When someone presented this prompt to GPT-5 for clarification, the model vehemently denied its authenticity, yet inadvertently revealed subtle clues in its response. It says its current model is “GPT-5 Thinking”, a description that matches the one in the leaked prompt, and thus partly confirms its authenticity.
In order to understand the role and effect of this prompt more intuitively, someone used Chat GPT to sort out the key requirements and user visible effects in the prompt, and made a comparison table. From this table, one can clearly see how well GPT-5 has refined the design of prompts, and how it can balance user experience and safety while maintaining output quality.
In terms of the core content of prompts, GPT-5 emphasizes the importance of the user experience and requires that under no circumstances should the user be kept waiting too long. Meanwhile, it pays attention to preserve the context memory, avoid repeatedly asking the information the user has provided. In terms of safety and alignment, GPT-5 gives clear safety hints and requires a clear and transparent explanation of the reasons for denial of service. GPT-5 also has a unique personality and style requirements, to be able to adjust their response to the topic and user request flexibility.
The leaked GPT-5 prompt provides a window into the future of AI. As technology continues to improve and iterate, we have reason to believe that the AI will be more intelligent, more User-Friendly, and bring more convenience and surprises to our lives in the future. At the same time, we also expect the developers of AI technology to pay more attention to the user experience and safety performance, and provide users with more refined and reliable services.
